Iva Jovic's French Open formula: Winning on court, fun off of it

PARIS -- It might be easy to forget that Iva Jovic is just 18 years old.

She is in only her second year on tour, but has already won a WTA title at the 500-level Guadalajara Open, reached the Australian Open quarterfinal -- and is ranked No. 17 in the world.

But while she almost always looks composed on the court, as she did during a 6-0, 6-3 dismantling of the far-more experienced Emma Navarro during the second round at Roland Garros on Thursday, so much about being a professional tennis player remains new to her. While it might look routine, she's learning as she goes.

And she is the first to admit that tennis can be a confusing sport at times.
